As of 30th June, Python 3.7 has reached end-of-life upstream: https://devguide.python.org/versions/#supported-versions This means there will be no new Python 3.7 patch versions released upstream, so no security updates or bug fixes. The existing buildpack deprecation message has been updated to reflect this, and now also mentions that support for building Python 3.7 apps will be removed in October 2023. In addition, the scripts and GitHub Actions workflows used to compile and upload new Python runtime versions have been updated to drop support, since there will be no new Python 3.7 releases for us to upload. GUS-W-13717141. GUS-W-13717143.

Since: - It has been end of life upstream since 2023-06-27, so is no longer receiving security updates. - The buildpack has been warning about its end of life in the build log output since 2023-02-08 (see #1404, #1460), and its deprecation was previously announced on changelog: https://devcenter.heroku.com/changelog-items/2530 - The upgrade from Python 3.7 to Python 3.8+ in most cases requires no changes to an application at all, or else some small dependency updates (compared to say the upgrade from Python 2 to 3). - Python 3.7 is not compatible with OpenSSL 3, and so only works on the Heroku-20 stack - which itself will be deprecated in 2024. - Any apps that must stay on Python 3.7 short term, can pin to the previous buildpack version (`v238`) as a stop-gap. This also unblocks updating setuptools and pipenv in the buildpack, both of which have dropped support for Python 3.7 in recent versions. Closes heroku/roadmap#198. GUS-W-12345803.
